Definitions

  • the present invention relates, on the one hand, to an installation for the recovery of a polluting fluid contained in the tanks of a cast vessel, and, on the other hand, to a specific conduit used for such an installation.
  • This recovery system includes a compartment in each vessel of the ship failed, this compartment containing several flow pipes and a float element capable of being ejected out of the sunken ship. More specifically, for each compartment, this system comprises a pollutant fluid discharge pipe having a first end connected to the tank and a second end connected to the float element. This second end can then be eradicated at a sufficient distance from the cast vessel using a cable to which the float element is attached. For each compartment, this system also has a suction pipe and an injection pipe both connected to the discharge pipe and respectively provided with a first end floating on the surface of the polluting fluid contained in the tank, and a weighted second end disposed in the bottom of said tank.
  • this system comprises a connecting pipe coming from a rescue ship on the surface and having, on the one hand, a first end connected by interlocking in the second end of the discharge pipe, and on the other a second end connected to a pump installed on the rescue ship.
  • pressurized water is injected from the rescue vessel into the bottom of the tank via the injection pipe.
  • the polluting fluid is then sent back to the rescue vessel via the suction pipe, the discharge pipe and the connecting pipe.
  • This recovery system nevertheless has a drawback consisting in the fact that, when the ship has sunk, it is not easy to access from outside the compartments housed in the tanks.
  • Another disadvantage lies in the fact that, although it is possible to provide for the installation of such compartments in the tanks during the construction of the ship, it is however very difficult to carry out such an installation on an existing ship.
  • the compartments being stored inside the tanks, sealing and safety problems can be raised.
  • this system necessarily providing, on the one hand, to pull the second end of the discharge pipe out of the tank, and secondly, to go up the second end of the injection pipe to the surface, it follows that the connection between the connecting pipe and the drain pipe is relatively complex to achieve. Finally, it is not necessary to ballast the second end of the injection pipe since the density of the water introduced under pressure is higher than that of the polluting fluid.
  • each of the compartments containing valves being located above the waterline of the sunken vessel, a ROV (remote controlled submarine robot) or a diver can access these compartments much more easily and thus proceed to the connection operations and control.
  • these compartments being preferably fixed on the deck of the ship, implantation on an existing ship is relatively easy, and any problems of sealing and safety are solved.
  • the end of a fixed pipe opens into each corner of the ends of the transverse vessel slice, and secondly, that each fixed pipe is connected to a valve at the level of its second end, it is no longer necessary to provide the rise of one end of the injection pipe to allow the introduction of pressurized water from the relief vessel.
  • the ROV or the plunger can directly command the opening at the choice of one or more valves housed in compartments accessible from outside the ship.
  • the fixed pipe or pipes associated with this or these valves therefore act as introduction pipes, the hydrostatic pressure seawater rushing through said valves, then penetrating along each of these fixed pipes, and finally being introduced into the transverse tank slice. Since seawater has a density higher than that of the pollutant, it follows that the latter is discharged by the seawater to the highest point of the transverse vessel slice. This polluting fluid is then introduced into at least one other fixed pipe, acting as a discharge pipe, the first end of which is in the highest end corner of the transverse vessel slice.
  • This pollutant fluid is then discharged along this fixed pipe towards the associated compartment, then discharged along the connecting pipe, to which the second end of the fixed discharge pipe is connected, in the direction of the surface where the vessel is located. rescue, and finally can be poured from the connecting pipe into the tanks of the emergency vessel using a pump mounted on it.
  • a first disadvantage lies in the fact that the fixed pipes make it difficult to clean the tanks. Indeed, the cleaning of a tank is usually carried out using a motorized device disposed in the center of the tank, and projecting a liquid against the constituent walls of the tank. In this case, the fixed pipes then constitute shields masking certain areas of the tank. In addition, the cleaning of the interior of the fixed pipes is itself relatively difficult to achieve. This problem is particularly noticeable in the case of ships carrying polluting chemicals for which the risk of contamination is not negligible.
  • the object of the present invention is to overcome the drawbacks mentioned above, and for this purpose consists of an installation for the recovery of a polluting fluid contained in at least one tank of a cast vessel, this installation comprising a plurality of ducts fixed in the vessel deck, each duct having a first and a second ends and may, depending on the grounding position of the cast vessel, be a means for introducing pressurized water into the vessel or a means of discharge of the pollutant fluid to the outside of the tank, characterized in that these ducts are positioned so that, on the one hand, their first ends open in the vicinity of each of the upper corners of the tank, and other their second ends are directly accessible from the outside of the sunken ship.
  • this hollow needle will be able, after opening / closing a set of valves housed in said hollow needle and in the specific tooling, to bring water under pressure to the low point of tank. At least one of the other ducts will then be able to recover the pollutant fluid, and for this will be connected, also with the aid of a specific tool provided with a suitable set of valves, to a recovery pipe connected to a rescue ship.
  • this hollow needle will be used for the recovery of the polluting fluid, and for this will be connected, using a specific tool provided with a suitable set of valves, to a recovery pipe connected to a rescue ship.
  • a specific tool provided with a suitable set of valves
  • at least one of the other conduits will, with the aid of a specific tool provided with a suitable set of valves, the introduction of pressurized water in the lower part of the tank.
  • each conduit is surmounted by a collar accessible from the deck of the ship.
  • This collar thus allows an easier connection with the specific tooling that is reported in case of sinking; as claimed in claim 8.

  • each duct 5 comprises a substantially tubular section 6 terminating in the upper part by a flange 7 closed successively, by a frangible disc 8 having a circular line of weakness 9, then by a protective plate 10.
  • the frangible disc 8 is for example secured to the flange 7 by means of bolts 40 disposed over the entire periphery thereof, and the protection plate 10 is for example fixed on the frangible disk 8 by means of bolts 11 arranged over the entire periphery of the latter, the bolts 40 being angularly offset by approximately 30 ° with respect to the bolts 11.
  • the assembly consisting of by the flange 7, the frangible disc 8, and the protective plate 10 then forms a second end accessible from outside the vessel 1.
  • the bolts 40 each have a rod protruding from the flange 7 so that a nut (not shown) can be attached to its end.

  • a plunger or an underwater robot removes the protection plate 10. Then, an underwater robot connects a first valve 17 open on the flange 7 through a first set of fastening jaws (not shown). A specific tooling 19 is then fixed in the first valve 17 by the undersea robot with the aid of a second set of attachment jaws (not shown).
  • This specific tooling 19 comprises a motorized perforating member 20 which is initially in the retracted position, as shown in FIG. figure 7 .
  • this piercing member 20 is then actuated so as to provoke the fracture of the frangible disc 8 at its line of weakness 9 after crossing the first valve 17 open. Subsequently, the perforator member 20 is raised in the retracted position and the first valve 17 is closed. The duct 5 is thus sealed again, and it is thus possible to disconnect the first valve 17. specific tooling 19 without causing the immediate introduction of pressurized water into the tank 4.
  • the end of the hollow needle 15 can then be inserted into the conduit 5, the complete introduction of the hollow needle 15 into the tank 4 being made possible after opening the first valve 17.
  • This hollow needle 15 is it equipped with a second valve 21 which is initially closed. Therefore, the pressurized water can not enter the tank 4 during the insertion step of the hollow needle 15 into the tank 4.
